' Application filed May 9,

To all whom it may concern: Be it known that I, SYDNEY DILLON, of

Edgewood, Allegheny county,Pennsylvania;

have invente a new and useful Metal-Transfer Apparatus, of which the following "is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which p v Figure 1 is a plan view showing my mi? proved apparatus, Fig. 2 is a sectional end viewofthe same; Fig.3 is a detailtview showingthe jaw clutch in its disengaged positio'n' 'a'nd showing the clutch:operating mechanism forming part of my invention;

and FimA is a similar view on a larger I scale showing "the clutch-operating mechanism.

My invention relates to apparatus employed in transferring rolled metal blanks of considerable length and weight such as rails, billets, blooms, etc, and theobject of the invention is to provide means for transfer-ring such blanks and improved means by which such transfer mechanisinis actuated.

A further object of the invention 15 to provide improved means by which the 1ifting arms for any one of a series of receiving or cooling beds located at different points in the length ,of the feed table may be operated by means'of a single motor and to provide means whereby the lifting arms when set in motion by the operator are automatic ally caused to raise and then lower and to remain: in their lowered position until the clutch-operating mechanism is again started by the operator. v In the drawings, 2 represents the skidsof one of the receiving or cooling beds, 3 rollers of a roller feed-table for delivering material along one side of the cooling beds and 4 represents the rollers of a feed-table bywhich the material is taken from the opposite side of the cooling beds. The feed- -table rollers. are driven in the usual manner through suitable gears and shafts (not "SlIOWIQ by means of any desired type of motor.

Each of the cooling beds is provided with lifting arms 5 by means of which the metal shaft (3 which is mounted in suitable hearings 7 and each of the arms 5 has a depend Specification of Letters Patent.

ing cam-lever or arm l\lounted"iji"-'bearings 9 and located beneath and to ouiif'side of the lifting arm shaft 6 is a cam sh'aft 10 and keyed orotherwise secured to this shaft 10 at points opposite the depei'idin'g" cam levers 8 are eccentrics or cams 11 WlllCllCOlltact with and actuate the dependih 'a i'lns i8 and lifting-arms 5 when the shaft: 'O'i's rotated. Secured to one'cnd of the" shaft 10 so as to be longitudinally movable on 'the shaft is one of the oppositely facihg"'clutcli disks 12 and 13 which form'thec'lutbhaby which'the shaft 10 is detacliably secured to the clutch Sliitft'll. Theclutch -disk"13 is secured to the clutch shaft 1 1 which is mounted in the bearings 15' and which is provided with a driving ear whcel 1G. 1.;

The inner face of the utch disk '12'which 15 secured on the end of the cam shaft" 10 so as to rotate with and also to belongitudh nally movable on this shaft is provided with aws 17 which engage with similar'jaws 18 on the opposite clutch disk 13. Around the jaws 17 on the clutch disk 12 is an annular surface portion 19 which is plan'e,and surroundin the lane portion 19 is an a'nnular cani sur ace 2 Mounted so as to be longitudinally movable in a bracket bearin 21 is a pin or shaft 22 havin an antiriction roller 23 rotatably secure to its-lower end. The roller 23 contactswith the. surfaces 19 and on, the inner face of the clutchi disk 12 to move and hold the jaws 17 out of engagement with the similar jaws 18-on the clutch disk 13. The upper end of the vertically movable pin 22 is connected by links 24 with the lever v25 which is provided with a counterweight 2'6 and one 'end of this lever is pivoted on the bracket 27 located on the upperrend ,of the bracket bearing 21, its opposite end being secured by a shown),

The clutch disk 12 is moved longitudinally on the cam-shaft 10 and into engagement with the clutch disk l3 bv" means of the yoke 28, the forked arms'of which are provided with antisfriction rollers 29 which contact with 'the' outer surface 30 of the clutch disk 12. The yoke 28 ispii oted on the shaft 31 and on the end of this shaft is a-counterweight lever 32 on which the counterweight 33 is adjustably' secured. The clutch driving gear 16 on the shaft 14 meshes with the gear 34 on. the counter shaft 35 and this counter shaft isdriven through the gear r l exible con- HOCblOIl to the operators hand lever,-:.(not

g eeaaaa which they are to be deposited. Two or more rails may be transferred from the roller'table to the cooling bed at one lifting operation or the rails may be transferred singly if desired. The motor 38 is started to rotate and the rail or rails are then moved on the feed roller's3 to a point above the lifting-arms 5 of the cooling bed towhich the materials are to be transferred. \Vhen the rails are in position, the operator, by means. of the operating hand lever through the flexible connection'and lever lifts the pin 22 and the roller 23 secured to its lower.

' with the clutch disk 12. l/Vhen the roller 23 is clear of the disk the counterweight 33 end until this roller is out of engagement through the shaft 31 and yoke 28 causes the clutch disk 12 to move on the cam shaft 10 until the aws 17 engage with the jaws 18 on the oppositely facing clutch disk 13. The

motor 38 through the clutch then causes the cam shaft 10 and the cams 11 to rotate and the cams contact with and raise the depending,arms 8 and lifting-arms5 until the lift ing-arms are in the position shown do'tted in Fig. 2, As the lifting-arms 5 are tilted the rails which are above them on the feed-rollers 3 are lifted on the arms and when'these arms have been raised to a point at or above the angle of re ose the rails will slide along the upper sur ace of the arms and will be deposited on the-skids 2 of the cooling bed. Asthe cams 11 are moved through the second half of their revolution the lifting-arms 5 are lowered untilthey reach the osi'tion "shown by full lines in Fig. 2. W men the operator has lifted the roller 23 on the pin 22 until it is out of engagement with the disk 12 and the counterweight 33 has automatically moved the disk 12 on its shaft to bring the jaws on the clutch disks into engement, the pin 22 and its roller 23 is in t e position shown by full lines in Fig. 4.

As 'the camshaft 10 is moved throughits revolution the roller 23 by engagement with the'cam surface on the inner surface of the clutch disk 12 automatically moves this disk out of engagement with the clutch disk 13 on the shaft 1 and holds the'disk 12 in its disengaged position until the operator again lifts the pin 22 and the roller 23 so as to per- Init the clutch disk 12 to be again moved o'nlthe shaft 10 into engagement with the clutch disk 13. After the lifting-arms have motor operates.

beenraisedand lowered another rail or rails are brou ht into position above these lifting arms an theabove described operation is repeated.

. he' lifting mechanism may be employed in transferring materials from one bed to another, and from a bed to a feed-table, and

may also be used in transferring from a feed table or bed into cars, and may be applied to many other uses within the scope of my invention. The lifting-armsfor a number of cooling beds may be simultaneously raised to deposit rails on each of the cooling beds or one cooling bed may befilled before the operation of depositing rails on other of the beds is commenced.

Instead of employing one cam shaft 10 which moves the lifting arms on a series of cooling beds, each of the. cooling beds may be provided'with a separate cam shaft 10 and clutch mechanism 1n which case each of the cam shafts will be driven through its cam shaft gear 16 which will mesh with a suitable gear on the counter-shaft, this countcr shaft bein stantly rotated by the motor 38.

The advantages of my invention will be apparent 'to those skilled in the art. The

geared to and con-' apparatus is simple and is easily kept in repair. One motor is employed to o erate the lifting-arms for a series of coo ing beds. By employing a rotary motor for operating the lifting-arms, the use of a fluid pressure motor is avoided. When the lifting mechanism is started by the operator, the arms are automatically raised and lowered and are kept in their lowered position until again set in motion by the operator.

I am the first to apply a rotary motor for use in operating the lifting arms of a transfer apparatus and am also the first to apply the automatic clutch operating mechanism to such apparatus and I intend to cover the same broadly in the claims.

Modifications in the construction and' arrangement of the parts ma be made. The by direct conlifting arms-may be raise tact with'the eccentrics or cams and other changes may be made within the scope of my invention.

I claim 1. The combination of feeding-in rolls arranged to feed work longitudinally, a receiving bed, arms oscillating .about 'a pivot arranged to transfer work laterally from the line of feed of the feeding-in rolls, a

motor adapted to operate continuousl and means associated w1th the motor an arms to oscillate the arms about the pivot, as the 2. Thecombination of feeding-in rolls arranged to feed work longitudinally, a receiving bed, a rock-shaft disposed-between the feeding-in rolls and the receiving bed, arms carried by the rock-shaft and oscillatiio in'g between theft'eeding-in rolls and the receiving'bedjna direction transvorseto the line of feed of the feeding-in rolls, a crank arm upon the rock-shaft, a cam shaft having a (-am working against the crank arm, a

motor adapted to operate continuous] and controlling means to connect and iscon-' nect the motor and cam shaft.

3. The combination of feeding-in rolls arranged to feed vork longitudinally, a receiving bed, oscillating arms arran 'ed to transfer work laterally from the hne of feedof the feeding-in rolls, a motor adapted to operate continuously, and means associated with the motor and arms'to oscil- 15 late the arms as the motor operates, said means includin a cam working against a crank arm, aml means for connecting -and (liswnnecting the cam and the motor;

In testimony whereof, I have hereunto 20 set my hand.
